A fire resistant textile material comprising a fire resistant textile material comprising a woven face fabric composed of fibres selected from: meta-aramid, para-aramid, polyamideimide and mixtures thereof; wherein the number of warp face threads, per unit width (cm) is greater than the number of weft threads, per unit length (cm). 1. A fire resistant textile material comprises a single woven warp backed fabric composed of fibres selected from: meta-aramid , para-aramid , polyamideimide , polybenzimidazole , polybenzoxazole and mixtures thereof;wherein the fabric comprises face warp threads and back warp threads, wherein the number of face warp threads per unit width (cm) is greater than the number of weft threads per unit length (cm); and wherein each back warp thread either interlaces or passes under successive weft threads so that the ratio of the total number of interlaced weft threads to passed under weft threads is in a range from 1:2 to 1:20.2. A fire resistant textile material as claimed in claim 1 , wherein the ratio is selected from: 1:2; 1:5; 1:8; 1:11; 1:14; 1:17; 1:20.3. A fire resistant textile material as claimed in claim 1 , wherein the back warp threads form a repeating pattern in which the total number of interlaced threads to passed under weft threads is an integral integer divisible by 3.4. A fire resistant textile material as claimed in claim 1 , wherein the back warp threads form a repeating pattern consisting of successively interlacing first weft threads followed by extending beneath an array of weft threads.5. A fire resistant textile material as claimed in claim 1 , wherein the back warp thread extends beneath an array comprising a number of adjacent weft threads claim 1 , wherein the number is an integer between 2 and 20 claim 1 , preferably between 5 and 14.6. A fire resistant textile material as claimed in claim 1 , wherein the face warp threads have an elongation at break greater than the elongation at break of the back warp or weft ...
